Abstract:

Wireless Sensor Network (WSN) based on the ZigBee protocol is the next generation of emerging sensor networks.ZigBee technology with high performance,low power consumption and low speed rate enjoys broad application prospects,such as industrial control.This study uses the ZigBee technology to establish the wireless network in smart home in stead of the traditional mode type with low power ARM11 as the core,embedded protocol stack as the data interface and embedded Web server as the gateway to improve the wireless node failure that affects information acquisition.Experiments show that the failure detection rate is 80% and the temperature detection error is 0.05 ℃,thus enhancing the security of the smart home and achieving the smart management of household life by the wireless sensor network.
